Latest version of the World Digital Magnetic Anomaly Map (WDMAM v.2.1) released
The last version of the World Digital Magnetic Anomaly Map (WDMAM v. 2.0) was released in 2015 (Dyment et al., EPSL, 2015; Lesur et al., EPS, 2016) with the mandate to update it using the same methodology when new data become available. The new version 2.1, compiled at 5 km interval, at 5 km altitud...
